What is the "central nervous system"?

Les Weiner (Former Chair of the Department of Neurology, University of Southern California) gives expert video advice on: What are the different areas of the spinal cord, and what are their functions?; How does pain work in the nervous system? and more...

Well, there is the brain. There is actually the brain, and the offshoot of the brain is actually the eye. The eye is an out-pocketing of the brain. So, it's really classified as the central nervous system. It's the same tissue as the brain. There's also the spinal cord, which has the input from the periphery that goes up to the brain, and it has the the impulses from the brain that go down into the periphery.
